While this is too late now as you have already got it off, I have a method that worked great. Although it is not as thought out as the 2x4, I literally just had the g/f stand on the brake rotor and all the assembly so to speak and push down on it. The front was a strong push and I could pull the shock out and as for the rears, well the drivers side I had to push with one hand, pull the shock with the other while she basically bounced for 20 seconds trying to get it low enough to get out. Although this seems way more effort, it is really rather simple. Oh the g/f only weighs 125 lbs so any one heavier would just make it that much easier. My bro just had to stand on it the first time we did it.
